MACHINE FOR WORKING UPPERS OVER LASTS.

Specification of Letters Patent. Patented Apr. ll3, d915,

Uriginal application filed April 19, 1909, Serial No. 490,848. Divided and this application filed May 28, 1910. SerialNo.563,907.

To all whom it may concern Be it known that l[, RONALD F. MCFEELY, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Machines for Working Uppers Over Lasts, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indieating like parts in the several figures.

This invention relates to machines for use in working an upper over a last and particularly to mechanism for working an upper into lasted position over and about the toe portion of .a last.

The invention is shown as embodied in a pulling-over and lasting machine of the type described in my prior application Serial No. 372,055 and the present application is a division of my application Serial No. 490,848, filed April 19, 1909, for improve ments in pulling-over machines.

Anobject of this invention is to provide an end lasting mechanism having certain advantages in addition to those of the mechanism shown in said prior application, particularly in the direction of greater range of adaptability to varying shapes of lasts and greater efficiency in operation. It has been found that while the wipers of said application have a wide range of movement for lasts occupying different positions and having diflerent shapes, as in the case of irregular right and left crooked lasts, yet a set of wiper plates which have an edge contour suitable for one shape of last will not force the upper inwardly into proper position against the shoulder of the innersole of a shoe which is much wider or narrower than that for which the plates are shaped.

that for which the other is shaped. In their use one set of wipers will force the upper snugly against the lip of the innersole about one part of the toe and the other will conform to another part and a great range of shapes is thus accommodated without removing the wipers and substituting others as it has heretofore been necessary frequently to do in the use of end lasting mechanism employing end embracing wipers.

Another feature of this invention consists in the provision of operating means for giving independent working movements to the different sets of wipers. As here shown the auxiliary wipers, as they may be termed for the purpose of designation Without implying any limitation, are mounted below the main wipers and, while being arranged for movement lengthwise of the shoe with the main wipers, have separate means for closing them. By this operating means the auxiliary wipers may be closed to complete the lasting of the toe in case the toe is of a shape to which the main wipers cannot conform throughout their working edge.

A further feature of this invention is found in lasting means which comprises wipers that are adapted to embrace and conform to the contour of the side faces of the toe portion of a last and are mounted for movement to wipe upwardly along the side faces of the last toward the edge thereof and comprises other wipers which are adapted to slide over the first mentioned wipers and inwardly over the last bottom to wipe the upper over the innersole while the first wipers hold it clamped against the outer sides of the last. By this arrangement the liability of the upper slipping back when the wipers begin to wipe inwardly over the last edge is avoided and a well defined angular edge may be formed instead of the rounded edge which is liable to result from the usual rubbing action of the same wiper upwardly and then inwardly over the last edge. The two sets of wipers may be the main and auxiliary wipers above described the latter of which are employed for clamping and holding the upper about the outside of the last while the main wipers first close in over the last bottom. Another purpose for which the auxiliary wipers may advantageously be used is to press the wire, which is commonly employed for binding the upper, into its seat under the main wipers and into holding relation to the upper which is pressed by the wipers against the lip of the innersole. For this purpose the wire may be drawn under the wipers while the mainwipers hold the upper in lasted position, and after the auxiliary wipers are more or less retracted, and then the wire may be forced by the auxiliary wipers into its binding position while being held down by the main wipers. It is also to be noted that the closing of the auxiliary wipers between the margin of the shoe bottom and the main wipers, while the latter are pressing down, serves further to draw in and tighten the upper over the edge of the last.

These and other features of this invention, including certain combinations of parts and more important details of construction, will be explained in connection with the following description of the mechanism in which the invention is shown as embodied and then pointed out in the claims.

Figure 1 of the drawing is a side elevation of so much of the machine as it appears necessary to show for disclosing the present invention. Fig. 2 is a plan View partly in section showing main and auxiliary wipers of different edge contours. Fig. 3 is a plan view showing the mainwipers closed about the side faces of a shoe to wipe the upper upwardly toward the shoe edge as indicated in the sectional view, Fig. 4, which is taken on the line 4-4 of Fig. 3. Fig. 5 is a view similar to Fig. 3 but showing the wipers closed in against the lip of the innersole to which the auxiliary wipers conform while the main wipers are too large for this contour. Fig. 6 is a section on line 66, Fig. 5. The upper pulling and adjusting mech anism may be the same as that shown in said prior application although an improved toe gripper which is curved to conform to the shape of the toe end of the last is shown in these drawings butfisp'ec'rfically, forms no part of this invention. This mechanism does not require to be herein described but reference may be had to said prior specification for further information than that found in these drawings. It should be understood, however, that this toe lasting mechanism is adapted for general use, separately from any other mechanism.

The toe lasting devices are carried by a head yieldingly upheld in its inoperative position and capable of being moved downwardly by a rack and pinion controlled by the lever 82, as fully described in said prior application. The lastin devices include the main plates 84, 85, of wliich the former are connected by the links 86 with an equalizing lever.87 pivoted to a rack bar 88, which is actuated by a pinion on a lever shaft 90, while the wiper plate is so connected to the rack bar 88 that it can yield backwardly and also can slide laterally with the plates 84 for adapting the contour of the acting edges of said plates to the shape of the particular last being operated upon. All these parts are fully described in said prior application and further explanation of them here is unnecessary. In addition to the wiper plates above described there are provided in accordance with this invention auxiliary wiper plates 94: located under the plates 84, as shown in Figs. 2 to 6. The auxiliary wip ers are pivotally connected to the central wiper 85, being conveniently secured to the same pivot pin that fastens the wiper plates 84 to the plate 85. By this arrangement the auxiliary plates partake of the movements of the late 85 both laterally and longitudinally of the shoe so that they are automatically positioned before the time arrives for them to be used. For actuating the auxiliary plates their outer corners are connected by links 96 with a cross bar or equalizing lever 97 within which is mounted an eccentric 98 which can be turned about a pivot pin 99 by a lever 100. The auxiliary wiper plates, which are thin as compared with the main plates, are adapted to he used after the main wiper plates have worked the upper substantially into position to be fastened and can be employed for crowding the upper, particularly at the corners of the toe, or the culfved portions between the toe end and sidesf'firmly into the angle between the innersole. 1 a

The auxiliary plates may and preferably will have a different edge contour from the plates 84, as is indicated in dotted lines in the drawings, to enable them to wipe the upper up to the shoulder of the innersole at the corners and sides of a shoe of different shape than that for which the main Wiper plates are formed, as for example, one that is wider or has a squarer toe. By the use of the two sets of plates a wide range of shapes and widths of shoes can be lasted without changing the wiper plates for a. different set of plates. As indicated in Figs. 3 and 4, the wipers may be used for rubbing the upper on the side faces of the last toward the edge thereof for stretching-the upper and conforming it to the shape of the last. When the wipers have been raised to the edge of the last the upper or main set of plates may be closed to bend or break the upper inwardly-over the last edge while-the lower or auxiliary set of plates continue to clamp the upper against the side of the last. In

, feather edge and the shoulder or lip of the been stretched up has no opportunity to slip .back while the edge is bein bent over and wiped down upon the shoe ottom. It

this use of the wipers, the upper which has mes es is also found that by the use of these auxiliary wipers difficulties are overcome which have heretoforebeen experienced in smoothly lasting the corners of the toe and in firmly securing these portions of the upper in the angle of the innersole by the wire binder used for that purpose.

One of the advantages incident to the provision of main and auxiliary wipers is that in the operation of placing or seating the binding wire the upper plates '84: may be employed to hold the wire from rising while the lower plates crowd the wire into its seat which those plates may have been employed for making before the wire was introduced.

In one use for which the described mechanism is adapted, the toe gripper will retain its hold on the upper while the wipers are employed for wiping the upper upwardly along the sides of the last and the end wipers 84 are manipulated to force the upper inwardly over the corners of the toe while the middle wiper 85 and the auxiliary wipers 94 are clamping the upper against the sides of the shoe at the edge. Thereafter the wipers will be further lifted to the plane of the shoe bottom and the spring 83 will force the middle wiper 85 and the adjacent ends of thecorner wipers forwardly to press the entire toe portion of the upper to the shoulder of the innersole. The lever 100 may then be manipulated to wedge the auxiliary wipers between the wipers 84c and the upper for i tightening the upper, or to press the upper against the shoulder of the innersole at points not well fitted by the main wipers, or to force into holding position a wire which may have been drawn in under the plates 84, 84, 85. It is to be observed that the auxiliary wipers may be repeatedly opened and closed. while the main wipers continue to hold the upper. Experience appears to indicate that this use of the auxiliary wipers will not be required for every shoe, but that they will need to be employed only in lasting particularly difficult work. Itwill'be observed that the auxiliary wipers are arranged so that they will need to be used only when required and are not in the way during the use of the main wipers.

The manner in which the improvements I herein described are to be employed has been made clear in connection with the description of the mechanism in which the in vention is shown as embodied.
